HAT -PRESSING MACHINE,

Application filed November is, 1927. Serial No. 233,566.

This invention relates to hat pressing machmcs and consists in certainimprovements in the hat pressing machine Patent No. 1,526,000 granted tome February 10, 1925, such ci ally to means improvements relating espebywhich the platen. orpacking of such a machine is n'iaintained at alltimes in proper relation to the other parts, thus to avoid inpiry to andreduce the wear am tear on the platen or packing and prevent its beingthe cause of injury to or improper functioning of the other parts.

The drawin In Fig. 1 so shows, much oil: a hat pressing ma,-

chine embodying the present improvements as is necessary for the presentdisclosure, the

same appearing partly in side elevation and partly in section; and ,p p

In Fig. 2 a plan of the platen and a certain The fixedstructure a,upstanding pillars 0, thereof, fixed matrix or mold (Z supported by thepillars and having the 111g cavity 1 and annular br1m-shapmgporcrown-shapthe rods b on which,

through the medium of a cross-head (not shown), is carried andvertically adprstable relatively to such support the structure includingthe elastic inflatable bulbous crownshaping die 0, having a removablecap 2' and coactive with said cavity (Z and its fluid-conductingstandard 7, are

all or may be all substantially in my patent aforementioned,

the same as excepting as will be hereinafter noted, as may also be withlike excep tion the elastic rubber annuand its casing m, formingarranged within the ch anand the endless fiat yielding brim-shapingplaten 0' fitted within said channel fore, the inner well as the portionm which reaches and having an inner perimeter conforming in shape to andoverlapping, thereflange k of support 70 as of thebag means,

into the crevice forineo tween said inner flange of the support and theinner perimeter of the platen.

The broken line A in Fig. 1 indicates a hat.

The platen,

when the'press is open, protrudes as usual somewhat from the cavitywhich receives it and is and outer walls means contains formed by theinner of support is and by the bagd in said. support.

set forth in y to the upper Continual operations of the machine whenconstructed in accordance with my said patent resulted in the pressureon the platen expanding it outwardly radially or in its 'own plane, inconsequence of which the platen not only became distorted and generallyunfit for further use but found itself proecting between the mold (Z andthe margin (wall 70') of the aforesaid platen-receiving cavity and sopinched and thus damaged by them and besides frequently, in the closingof the'press, left a crevice between them so that a blow-out of the bagmeans followed. I have sought to overcome this defect, and this I haveaccomplished as follows: The

outer flange or wall 70 of the channeled sup ent conformation, and alsoof one bag'means for another when occasion requires, it is of coursebest that that portion of the flange in which has the conical surface 70be separable from the remainder of the flange; such portion of theflange is shown as a ring lshaving a lateral flange 70 and secured tothe flange k of the channeled support by bolts.

In consequence of this construction it is i found in practice that thereis no tendency under the pressure of the co-acting pressure structuresfor the perimeter portion of the platen or any part of such portion toproject itself between the margin of its cavity and the matrix or moldcl, the platen therefore does not in use as readily become radiallyoutwardly distorted or, as an incident of such distortion, become jammedor pinched as explained between and by such margin and mold or cause theexistence of any crevice between them which would permit a blow-out ofthe bag means to result. This is largely due to the upwardly beveledform of the outer perimeter of the platen which, forming with the top orsurface of the platen an obtuse angle rather than a right angle or less,is not conducive portion of the perimeter expanding so as to overlap themargin of its said cavity, butrather results in any radial expansionwhich takes place doing so in a brim-supporting crowd such perimeterdownwardly, which bulgewhose peak or maximum girth is below the level ofthe top of such cavity. It

is also of course due to the mentioned overhang tending, by receivingthe contact of the beveled perimeter of the platen, to cam or platenwould in a few operations under radial expansion bend upward at itsmargin 1 and so come to project itselfon radial expansion between themold (Z and the nmrgin of the platen cavity. But by the presentconstruction it is not impracticableto superimpose the packings becausethe mentioned Qoverhang acts as a lock-to hold down the tion', what Iclaim is:

topmost packing and .prevent, it from projecting itself between the moldand said margin of the platen-cavity.

Having thus fully described my inven- "I. In combination, with theopposing pressure-exerting structures of a hat pressin machine, onehaving a platen-receiving cavit and the other a mold o )osed to and y loverhanging the margin of the cavity, a

yielding brim-supporting platen arranged in and protruding from thecavity and having its perimeter beveled at an angle obtuse to itsbrim-supporting surface.

' 2.111 combination, with the opposing pressure-exerting structures of ahat pressing machine, one having a platen-receiving cavity and the othera mold opposed to and overhanging the margin of the cavity, a yieldingbrim-supporting platen arranged in and protruding from the cavity andhaving its perimeter beveled at an angle obtuse to its brim-supportingsurface, the first structure having an overhang arranged to receive thecontact of the beveled perimeter of the platen on expansion of thelatter in its own plane.

In combination, with the opposing pressure-exerting structures of ahat pressing machine, one having a platen-receiving cavity and the othera mold opposed to and overhanging the margin of the cavity, a yieldingbrin'i-supporting platen arranged in and protruding from the cavity andhaving its perimeter beveled at an angle obtus to its brim-supportingsurface, the first structure having an overhang arranged to receive thecontact of the beveled perimeter of the platen on expansion of thelatter in its own plane and also having the surface of saidoverhangingwith which the platen perimeter so contacts pitched at substantially thesame angle as the bevel of such perimeter.

In testimony whereof I afiix my signature.
